    The raw material for a $2 trillion circular economy is already flowing through recycling facilities. But how do we capture and use it? Rebecca Hu-Thrams, co-founder and CEO of Glacier, is deploying AI-powered robotic sorters at material recovery facilities (MRFs) across the country, processing recycling for one in 10 Americans. Her robots use computer vision trained on more than 3 billion images of waste to identify and sort over 70 different materials—picking 45 items per minute, 24/7, in conditions that would exhaust or injure human workers. As much as 80% of what Americans put in blue bins never gets recycled. The culprit is outdated technology at MRFs, the vast sorting operations struggling with a labor crisis so severe that facilities often refill the same sorting job five times a year. The work is dangerous, with injury rates twice that of construction. Rebecca, a first-generation American who grew up washing margarine tubs for reuse, saw an opportunity to apply cutting-edge technology to what she calls "the most demented form of manufacturing on the planet." The results are tangible. At oneDetroit MRF, an AI camera on a residue line revealed the facility was losing massive amounts of PET bottles to landfill, material they suspected was slipping through but had never quantified. By adding a single sorter based on that data, they achieved a two-thirds drop in PET sent to landfill and earned $138,000 in additional annual revenue.

    But Glacier's robots do more than sort. They create an intelligence layer for the circular economy, generating data about what's actually in the waste stream—down to specific brands and packaging designs. Amazon, which has invested in Glacier through its Climate Pledge fund, is using this data to understand what design features make packaging easier or harder for AI to detect, moving from "technically recyclable" to "provably recyclable." With extended producer responsibility (EPR) laws spreading across the U.S., this kind of brand-level accountability will become table stakes. Rebecca notes that EPR has improved recycling rates by over 40 percentage points in parts of Europe. Glacier's vision is to transform recycling from a reactive cost center into advanced manufacturing, built on three pillars: a reliable data layer, consistent automation, and higher-quality feedstock. "MRF managers show up to work, turn on the lights, and hold their breath and wait to see what new, crazy things come down their conveyor lines," she said. "What I hope is true for recycling in the coming years is that producers are making things designed to be really easy to recycle."

    We're still in the early steps of a long recycling evolution, but the gap between where we are and a truly circular economy may close faster than the past 60 years of recycling's progress would suggest. You can learn more about Glacier at endwaste.io.

  • Examining Colorado's First-Of-Its-Kind EPR Oil Recycling Program With David Lawes

    Examining Colorado's First-Of-Its-Kind EPR Oil Recycling Program With David Lawes

Read along with this episode.Americans dispose of approximately 1.3 billion gallons of used motor oil annually, but only about 800 million gallons get recycled, and most of that is burned as fuel rather than re-refined into new oil. The plastic packaging oil comes in is more problematic: most curbside programs won't accept them because residual oil contaminates other recyclables. What happens when the companies that make motor oil embrace extended producer responsibility (EPR) laws that require recycling the oil and the containers it comes in? David Lawes, CEO of the Lubricants Packaging Management Association (LPMA), is leading what could become a national model for extended producer responsibility. Colorado just became the testing ground. In September 2024, five major oil companies—BP Lubricants, Chevron, ExxonMobil, Shell, and Valvoline—founded LPMA as an independent producer responsibility organization.

    Colorado gave producers a choice: join the Circular Action Alliance, which manages all packaging and printed paper recycling in the state, or develop their own sector-specific program that demonstrates better outcomes. LPMA chose the independent path, arguing that petroleum packaging requires specialized handling that general-purpose programs can't provide efficiently. Lawes brings two decades of EPR policy experience to the role, including a decade regulating EPR programs in Canada. The program he ran in British Columbia achieves a 96% recycling rate for oil containers—compared to less than 1% in most U.S. states. "This is not about skirting the law or finding an easier pathway," Lawes explains. "It is about meeting the same results in an industry-friendly way."If Colorado's model works, it could reshape EPR programs nationwide. We discuss why petroleum packaging can't be managed through curbside programs, what lessons from Canada's more developed EPR system apply here, and whether the U.S. needs national recycling standards to harmonize the patchwork of state regulations.

  • Star's Tech Hando Choi On Inventing A Low-Carbon, Low-Chloride De-Icer Made From Star Fish

    Star's Tech Hando Choi On Inventing A Low-Carbon, Low-Chloride De-Icer Made From Star Fish

    Read along with our transcript.

    What if the solution to winter's infrastructure corrosion and environmentally benign home sidewalk de-icing was an invasive starfish being thrown back into Korea's coastal waters? Hando Choi, president of Star's Tech, joins the conversation to explain how one region's invasive species problem can become another's environmental breakthrough. The company developed ECO-ST, a de-icing product made from starfish skeletons that not only melts ice faster than conventional rock salt but also reduces the chloride pollution that causes billions of dollars in damage to roads, bridges, and vehicles every winter.

    Meanwhile, in Korean waters, the Northern Pacific sea star has become such a menace to shellfish aquaculture that the government purchases 3,000 to 4,000 tons annually to control populations. Stars Tech upcycles about 10% of that collected material, extracting the porous calcium carbonate structures that give starfish their shape and their remarkable ability to store and release chloride. The technology began as a high school science project when founder and chief scientist Seungchan Yang experimented with natural pore structures to control ion release, eventually connecting that research to the negative impacts of conventional deicers while studying at Seoul National University.

    The economic case is compelling once you factor in the full cost of ownership. While ECO-ST runs $465 to $650 per ton compared to $100 to $150 for commodity rock salt, salt itself accounts for less than 5% of most winter maintenance budgets. The Isaac Walton League of America estimates that infrastructure damage from road salt ranges from $30 to $300 per ton used. Stars Tech's simulations based on U.S. municipal data show ECO-ST can deliver up to 5,000% ROI over time when lower infrastructure maintenance costs, fewer reapplications, and ESG compliance benefits are factored in.

    ECO-ST is available on Amazon in the U.S. and Canada, with retail partnerships launching this winter. You can learn more about Stars Tech at starstech.co.
